So i'm having alot of issues with my AAZ so i'm picking up a 171000km one for 200$, i've seen it running so I know it works, when I went to look at it today the belts are off of it, when he was turning it over to make sure it wasn;t seized I noticed the Pulley on the Crank was wobbling but has no play in it...is there something wrong with the Crank? or just the pulley?
